METHOD FOR ESTABLISHING ISO LINK, AND BLE DEVICE

WIPO Patent Application WO/2021/092859

A1

The present application provides a method for establishing an ISO link. The method is used for establishing an ISO link between two Bluetooth low energy (BLE) devices, and an ISO link can be established more flexibly. The method comprises: a master device in the two BLE devices configures parameter information, the parameter information being used for the master device to establish an ISO link with a slave device in the two BLE devices; the master device scans a broadcast message from the slave device according to the parameter information, the broadcast message being used for establishing the ISO link; if the broadcast message is scanned, the master device sends an indication message to the slave device, the indication message carrying time information used for data interaction between the master device and the second device; the master device performs data interaction with the slave device on the basis of the time information; if at least one data interaction succeeds within a preset number of ISO intervals, the master device determines that establishment of the ISO link is completed.
